Buying Guide

Settling for a single brand of fertilizer is no simple task. But there are some things consumers should know before buying.

Determine the Type of Organic Lawn Fertilizer

Organic Lawn Fertilizer is divided into three types mainly-plant-based, animal-based, and mineral-based fertilizer. Plant-based fertilizers condition the soil but don’t last long. Animal-based add nitrogen to the soil and work well at the beginning of planting season. Mineral-based fertilizers add nutrients to the soil and change its PH.

The fertilizer can also be a dry or liquid mix. Liquid fertilizers are easier to apply and take effect quickly than a dry mix. Users only scatter the dry mix evenly, which means it’s not absorbed as fast.

Coverage Area

How much lawn needs to be covered? That will help determine which lawn fertilizer will be enough for the coverage area.  Too little, and the lawn won’t experience full benefits.  A few brands provide huge coverage areas per bag, which makes them an excellent choice for an extensive lawn.

Nutrients

The best organic lawn fertilizer should offer much-needed nutrients to the soil, which leads to a stronger and greener lawn.  Choose a fertilizer with ingredients like potash, phosphate, and nitrogen. Others have animal-based nutrients, which could also be helpful. 

Weight of the Bags or Bottles

A heavy bag or bottle will make it challenging to empty out compared to a lighter one. When selecting a Lawn Fertilizer, don’t forget to compare weight and coverage area as some provide a large coverage area and low overall weight. That makes the work of applying it easier. 

Consider the price of the Fertilizer

The cost of fertilizer differs from one brand to another. Quality fertilizers are available at a reasonable cost, but there are other expensive ones that have a variety of nutrients and provide large coverage areas.  Find one that fits the budget for the project.

FAQ

How Do I Use Organic Lawn Fertilizer?

If you get a liquid fertilizer, all you need is to spray it around the lawn, but a dry mix fertilizer needs to be scattered across the lawn evenly. 

Is There a Difference Between Regular Chemical Fertilizer and Organic Fertilizer?

The only difference is that the organic Lawn Fertilizer doesn’t have harmful toxins or chemicals, it only has plant and sometimes animal-based nutrients.  That makes it safe for people and the environment. 

How Will I Know if the Fertilizer works

Proof that the product works comes when plants and grass grow. This is an indication that the fertilizer is enriching the soil and providing nutrients for growth.
